Weight of Diamonds & Gems
CARATS Abbreviated "ct." and spelled with a "c" is a measure of weight used for gemstones. One carat is equal to 1/5 of a gram (200 milligrams). Stones are measured to the nearest hundredth of a carat. A hundreth of a carat is also called a pointer. Thus a .10 carat stone can be called either 10 pointers, or 1/10 of a carat. Small stones like .05, and .10ct are most often referred to by pointer designations. Note that karat with a "K" is a measure of the purity of a gold alloy. A one carat round diamond of average proportions is approximately 6.5mm in diameter. Note that this relationship of weight and size is different for each family of stones. For example ruby and sapphire are both heavier than diamond (technically, they have a higher specific gravity, so a 1 carat ruby or sapphire is smaller in size than a on carat diamond.
POINTER / Cents: The weight of smaller diamonds is often expressed as pointers, not carats. There are 100 pointers in a carat. Another way to look at it is to say that each pointer equals 0.01, or one-hundredth, of a carat.
